Medicament delivery system

A medicament delivery system comprising:

• a non-sealing nasal interface configured to deliver an asymmetric flow of gases to nares of a patient, the non-sealing nasal interface comprising a gases inlet;
• a nebuliser comprising a medicament inlet port and in fluid communication directly or indirectly with the gases inlet, the nebuliser configured to deliver a nebulised substance into the non-sealing nasal interface;
• the medicament delivery system defining a flow path between the medicament inlet port and the non-sealing nasal interface via the gases inlet,
• wherein the nebulised substance is configured to mix with ambient air to form at least part of the asymmetric flow of gases delivered to the non-sealing nasal interface.

A respiratory therapy system comprising:

• a liquid medication source;
• a gas delivery apparatus configured to provide respiratory therapy to a patient, and
• a medicament delivery system comprising:
• a non-sealing nasal interface configured to deliver an asymmetric flow of gases a patient's nares, the non-sealing nasal interface comprising a gases inlet;
• a nebuliser and/or a medicant delivery chamber directly or indirectly in fluid communication with the liquid medication source and the gases inlet, the nebuliser configured to nebulise liquid medication from the liquid medication source and deliver nebulised medication to the non-sealing nasal interface, wherein the nebulised medication is configured to form at least part of a gases flow delivered to the non-sealing nasal interface.

A medicament delivery system comprising:

• a non-sealing interface comprising a first nasal delivery element and a second nasal delivery element, wherein the first nasal delivery element is larger than the second nasal delivery element such that the first nasal delivery element and the second nasal delivery element are configured to deliver an asymmetric flow of gases to a patient's nares;
• a conduit having a length of less than 1000 mm and in fluid communication with the non-sealing interface;
• and
• nebuliser in fluid communication with the conduit.
